Limitations of Refracting Telescopes

Lenses create a type of image distortion known as chromatic aberration. This occurs because as light passes through a lens, different colors are bent through different angles (like in a prism) and brought to a focus at different points.

Hope it helps you dear!!!☺️❤️✌️⚡

Answer:

Problems with Refracting Telescopes

Chromatic abberation. The red and blue light focusses at different locations creating coloured halos. This occurs because the path taken by blue light through glass bends more than red light. ...

Lens distortion. A very large glass lens will tend to become distorted due to its own weight.
